Abstract

Gas-for-use considering energy storage The elastic scheduling method for the electric coupling comprehensive energy system comprises the following steps: selecting a gas-to-gas system according to selected gas-to-gas; electrical coupling integrated energy system and input gas- The structure and parameters of the comprehensive energy system are electrically coupled; establishment of gas Electrically coupling the comprehensive energy system equipment operation constraint and the cold / power supply and demand balance constraint; calculating an energy storage standby capacity rolling calculation stage; optimal scheduling of the day-ahead economic scheduling stage is carried out; and carrying out optimization scheduling of a real-time operation stage. The invention is based on solving the problem of gas-to-gas The optimal scheduling problem of an electric coupling comprehensive energy system is solved, the complementary coordination effect of electric driving equipment and gas driving equipment is fully considered, the response capacity of an energy storage device under the emergency condition is brought into play, and energy storage standby gas-gas is established and considered. And electrically coupling the multi-stage elastic scheduling model of the integrated energy system to obtain a system day-ahead scheduling plan and a load recovery scheme when a fault occurs.
